Windows only: Got a widescreen monitor and want to take full advantage of every last pixel? Freeware application Sizer resizes windows to pixel-specific sizes through the right-click menu so that rather than wasting screen real estate with maximized windows, you can fit as much information on your desktop as possible. Similar to previously mentioned GridMove, Sizer should also come in handy for web designers who need to test sites at different sizes (we've actually mentioned that aspect before). You can resize any window with Sizer by right-clicking that window's maximize button, right-clicking when a resize cursor is showing, or by right-clicking the Sizer system tray icon. Sizer is freeware, Windows only.
